Solution of two volatile liquids A and B obey Roalt's law. At certain temperature, it is found that when the toal pressure above a solution is 0.53 bar. The mol fraction. A in the vapour is 0.45 & other liquid is 0.65. What are the vapour pressures of the two pure liquids at the given temperature?

Heptane and Octane form an ideal solution at 373K the vapour pressure of the pure liquids at this temperature are 105.2 kPa respectively. If the solution contains 25g of heptane and 28.5g octane, calculate mole fractions of octane in vapour phase.
